As the name implies, currency speculation is buying and selling digital currency. There are two investment methods of money speculation: short-term money speculation and long-term money speculation. Short-term speculation refers to quick buying and selling, while long-term speculation refers to holding digital currency for a long time and throwing it out when it reaches the expected value. The two ways of speculating money are the same, but the time of holding digital currency is different.
